Metal deska world leader in additive manufacturing technologies for mass production, announced the launch of the X-Series range of binder jetting 3D printers for metal and ceramic powders in a wide range of particle sizes. The X-series binder jet 3D printers actually come from the ExOne line of printers. But through the acquisition of ExOne last year by Desktop Metal, its printers are re-launched with Desktop Metal’s award-winning build preparation and sinter simulation software applications. Additionally, Desktop Metal’s experienced global support team will now support the X Series.

The patented Triple-ACT – advanced compaction technology for distributing, spreading and compacting powders during the binder jetting printing process – enables X-Series binder jetting 3D printers to take a unique approach to binder jetting binder. This open hardware platform architecture enables bonding of a wide range of powders with D50 values ​​ranging from 3 to 100 microns.

The Triple ACT system addresses three of the most difficult aspects of (1) creating a thin, even layer of metal powder for a print job, (2) distributing, spreading, and (3) compacting the powders fine.

X Series Binder Jetting 3D Printers

  • InnoventX™, is a low cost, entry level binder jetting system ideal for academic studies, R&D and low volume production,
  • X25Pro™, with a build volume of 400 x 250 x 250 mm, is an accessible and productive mid-size solution that is already used for mass production worldwide (15.75 x 9.84 x 9.84 inches),
  • The X160Pro™ is the world’s largest metal binder jetting system, with a build volume of 800 x 500 x 400 mm (31.5 x 19.7 x 15.8 inches).

“Desktop Metal’s X-Series printers give customers more choice than ever when it comes to binder jetting additive manufacturing. Our team is aggressively moving to move additive manufacturing into mass production through a focused strategy of production-capable printers, high-performance materials, and key applications. Binder jetting is the key technology that delivers all the benefits additive manufacturing has to offer at scale, from waste reduction to more efficient and lower-risk supply chains.

– Ric Fulop, co-founder and CEO of Desktop Metal

Binder jetting is widely considered the fastest method of high-volume metal 3D printing. The process, which was first patented at the Massachusetts Institute of Technology by Ely Sachs, professor of mechanical engineering and co-founder of Desktop Metal, prints digital part designs by depositing a binder into a bed of metal particles, sand , ceramic or wood. using industrial inkjet printheads, creating batches of solid parts one thin layer at a time.

X-Series printers consistently produce tight dimensional tolerances and densities of 97-99% or greater, matching or exceeding metal injection molding or gravity casting. Directly out of the furnace, surface roughness values ​​as low as 4 m (Ra) can be achieved.
